For assignments that require the group to work through a process together to answer
each
question, you should define roles and let your students make only a few (3-5) submissions.
The submissions limitation helps all group members take the work seriously and encourages
your
students to think carefully before they submit their responses.
Well-defined roles help your students to work productively together; preferably students
should change roles during the term in order to practice the skills required for each
role.
Common roles for 3- and 4-person groups are described in the following table.
